If you don't want to piss me off, don't say to me, "I love my job!"
Maybe it's just that I know too many people in medicine, but it seems like only people in medicine seem to say this. Notably, I remember on one OB call in med school, the intern was running around like a crazy person all night delivering babies, definitely getting zero sleep, and at one point she said completely earnestly and to my complete befuddlement, "I love my job!"
(My private response: "Is that why you act like a bitch all the time?")
Most people don't really love their jobs. That's why it's called a job. You might like it. You might love some aspects of a job. But I feel like "love" is an emotion that should be reserved for people, not a place where you are obligated to go 5+ days a week.
There were times in the past when I said I loved my residency. But I didn't really. I mostly felt peer-pressured by all those job-loving liars out there. Plus it was so much less awful than my internship, it didn't feel like a total lie to say I loved it. Comparatively, I loved it because I didn't hate it with every fiber of my being.
So yes, I suspect a lot of the time when people say they love their jobs (or med school or residency), it's disingenuous. Either they're trying to convince themselves or they're trying to feel superior to other people who hate their jobs. But even if that's not the case, it's still an obnoxious thing to say, considering most people don't love their jobs. It would be like saying how much you love being a mother in a room full of infertile women. Or me blogging about how much I love being skinny, which I know would really piss off one or two of you in particular.
And if you still insist that you love your job... well, maybe you and your job should get a room.
